Fiber Optic MicroModems – For Serial Data Conversion Applications
VERSITRON’s M62xxD and M82xxD MicroModem Series provide fully transparent fiber optic transmission for data, clock and control signals. MicroModems provide synchronous or asynchronous, continuously variable, data transmission from 1 bps to 5 Mbps. Mode of operation is either full duplex or simplex. Small enough to install directly to data terminal and communications equipment, these modems offer versatile solutions and complete transparency for data communications.
M82xxD modems provide handshaking control signals associated with RS-232, RS-423 and MIL-STD-188-114A (Unbalanced). M62xxD modems provide handshaking control signals associated with RS-530, RS-422, and MIL-STD-188-114A (Balanced). RS-449 or V.35 standards are also supported with the use of M62xxD modems and specific adapters. Basic operation involves multiplexing the control signals along with the clock and data signals and transmitting the combined signal to the remote unit.
At the remote end the combined signal is de-multiplexed and applied to the electrical interface. The electrical interface will be a DB25F (DCE) if connecting to a terminal (DTE) interface. It will be a DB25M (DTE) if connecting to a modem (DCE) interface. LC connectors are standard for the fiber interface.
